Answer:

75°C

Explanation:

Answer: 75°C because KCL at 75°C goes into 50g in Solubility in 100g water. TRUST ME ITS RIGHT.

A 10.0 g-sample of liquid water absorbs 50 cal of energy when its temperature increases from 13 °C to 18 °C.

Heat is a form of energy resulting from the difference in temperature between two bodies.

A sample of water initially at 13 °C, absorbs energy in the form of heat and its temperature increases to 18 °C.

We can calculate the amount of heat absorbed using the following expression.

Q = c × m × ΔT

Q = 1.0 cal/g°C × 10.0 g × (18 °C - 13 °C) = 50 cal

Heavy water contains 20% hydrogen by mass and 80% oxygen by mass.

Heavy water is water which contains the heavy isotope of hydrogen, Hydrogen-2 in its molecules.

The mass of heavy water is greater than that of water.

The molar mass of heavy water is 20.0 g

The percentage composition of the elements in heavy water are as follows:

Hydrogen = 2 × 2g/20 g ×100% = 20%

Oxygen = 16g/20g × 100% = 80%.

Therefore, Heavy water contains 20% hydrogen by mass and 80% oxygen by mass.

Answer:

its the same thing as 3 x3 or 3+3 it always come´s back as 9 or 6 Because of life

Explanation:

Answer:

3.50 Mol/L or M

Explanation:

450 mL / 1000 = 0.45 L

1 mole ------- 126.751 g

? mole ------- 200 g

moles = 200 * 1 / 126.751

moles = 200 / 126.751

= 1.57789 moles FeCl₂

M = n / V

M = 1.57789 / 0.45

= 3.50 Mol/L or M

Answer:

See Below.

Explanation:

Recall that molarity is defined by moles of solute over liters of solution (mol/L).

Therefore, to make 90.0 mL of 2.0 M MgSO₄, we will need:

[tex]\displaystyle 90.0\text{ mL} \cdot \frac{2.0\text{ mol MgSO$_4$}}{1\text{ L}} \cdot \frac{1\text{ L}}{1000\text{ mL}} = 0.18\text{ mol MgSO$_4$}[/tex]

Convert this amount to grams. The molecular weight of MgSO₄ is 120.38 g/mol:

[tex]\displaystyle 0.18\text{ mol MgSO$_4$} \cdot \frac{120.38\text{ g MgSO$_4$}}{1\text{ mol MgSO$_4$}} = 22\text{ g MgSO$_4$}[/tex]

Therefore, to make the solution, we can add 22 grams of MgSO₄ into a graduated cylinder, then mix and dilute the solution with distilled water until we reach 90.0 mL.

Answer:

See below

Explanation:

MgSO4 mole wt = 24.3+32+16*4 = 120.3 gm

 for 90cc of 2M:

90/1000 * 2 * 120.3 = 21.66 gm

take 21.66 gm of the solid and dilute with water to 90 ml

Answer:

A. it conducts electricity

Explanation:

A. Since Nitric Acid is a strong acid, which means it is a strong oxidizing agent, this makes Nitric Acid a good conductor of electricity.

B. Basic solutions are only going to form OH⁻ ions. A Nitric Acid solution will form H⁺ ions.

C. Alkaline substances (pH greater than 7) are more likely to turn blue, so HNO₃ would turn that blue into a red color.

D. I don't know much about phenolphthalein , all I know is that is is pink in Alkaline solutions (basic) and colorless in acidic solutions.

The free energy change for the hydrolysis of ATP by using the equation ATP(aq)+H2O(l)→ADP(aq)+Pi(aq) is -64362.77joules.

We can calculate the free energy change of reaction by using the standard free energy by using the below link:

ΔG = ΔG⁰ + RTlnQ, where

R = ideal gas constant = 8.314 J/mol.K

ΔG⁰ = standard free energy = -46.5 kJ = -46500 J

T = temperature = 298 K

Q = ratio of the products to reactants for the given chemical reaction

Q = [0.0019][0.0038] / [0.0089] = 8.1×10⁻⁴

On putting values on the above equation, we get

ΔG = -46500 + (8.314)(298)ln(8.1×10⁻⁴)

ΔG = -46500 + (2477.5)(-7.21)

ΔG = -46500 - 17862.77

ΔG = -64362.77

Hence required value of free energy change is -64362.77 joules.

Answer:

2.5 X 10^-43

Explanation:

CoS> Co + S

Co=X

S=X

X= 5.0 X 10^-22

Ksp= [X][X]

Ksp= [5.0 X 10^-22][5.0 X 10^-22]

Ksp= 2.5 X 10^-43

The Ksp for CoS is calculated as 2.5 × 10⁻⁶³ (mol/L)². This value represents the equilibrium constant for the dissociation of CoS in water and indicates the extent of its solubility in the solution.

The molar solubility of CoS is given as 5.0 × 10⁻²² mol/L. In the chemical equation for the dissolution of CoS in water, it dissociates into Co⁻²⁺ and S²⁻ ions.

The solubility product constant (Ksp) expression for CoS is written as:

Ksp = [Co²⁺] * [S²⁻]

Since CoS dissolves completely to form one Co²⁺ ion and one S²⁻ ion, we substitute the molar solubility values into the Ksp expression:

Ksp = (5.0 × 10⁻²² mol/L) * (5.0 × 10⁻²² mol/L)

Ksp = 2.5 × 10⁻⁴³ (mol/L)²

Therefore, the Ksp for CoS is calculated as 2.5 × 10⁻⁶³ (mol/L)². CoS has an extremely low solubility in water, resulting in an exceptionally small Ksp value.

Answer:

Total pressure increased

Explanation:

When gas C is added in the vessel then number of mole increases and number of collision depends on the number of molecules present in the vessel and on adding gas C ,mole also increases hence  number of collision increases therefore pressure also increases because number of collision increases.

Total pressure increases.

Answer:

9.59 atm

Explanation:

Use ideal gas law    PV = n RT

 V = 5.34 L    n = 1.82 mole   T = ( 69.58+ 273.15) = 342.73 K

         R = .082057  L-Atm/(K - mole)

P  = n RT / V = 9.59 Atm

Based on the mole ratio of the reaction, 30 moles of NO2 will be produced from 15 moles of oxygen.

The mole ratio of a reaction is the ratio in which moles of reactants combine with themselves to form moles of products.

The equation of the reaction is given below:

[tex]2 NO (g) + O_2 (g) ---> 2 NO_2 (g)[/tex]

The mole ratio of NO2 to oxygen is 2 : 1

Molles of NO2 produced from 15 moles of O2 = 15 × 2 = 30 moles
